[1]} used a simplification to determine the lithospheric pressure due to the small size (R = 15 km) of their main test objects, as the contribution of the lithospheric pressure to total pressure is insignificant for small objects. This was replaced by Eq. REF  which gives reliable results for larger objects, too. Using this method the reaction rate becomes lower which makes a more significant difference for larger objects.
We compare our results with the [1]} litospheric pressure values in Fig. REF .
